ARCGIS 9.1 Licensing server not valid

We retired an old server that was running the ARCGIS licensing manager for 9.1. Was running fine.

Installed the license manager, and senitinel key with new license file from Customer Service.

The "new" computer is running Windows XP 32-bit SP3. I've moved the license manager before, and as long as was up and running, there were no issues.

On the computer with the license manager, When I display the hardware key status, it shows:



The Sentinel driver is installed and running.
Sentinel Driver Version PD-7.150
ESRI_SENITINEL_KEY=37102848

When I check the License Manager the status is as follows:

--------

--------
Flexible License Manager status on Tue 4/23/2013 15:54

[Detecting lmgrd processes...]
License server status: 27004@labgx280
License file(s) on labgx280: C:\PROGRA~1\ESRI\License\arcgis9x\TIFFLZW9.lic:C:\PROGRA~1\ESRI\License\arcgis9x\Viewer9.lic:

labgx280: license server UP (MASTER) v7.0

Vendor daemon status (on labgx280):

ARCGIS: UP v7.0

Feature usage info:

Users of TIFFLZW: (Total of 1 license available)

Users of Viewer: (Total of 4 licenses available)

These are the same version that were working on the previous computer running License Manager.

I DID test from the client machine using a TCP tool and port 27004 is indeed listening.

connecting to labgx280 server and port 27004

Port Available

All firewalls are turned off. Antivirus has been disabled. I'm at a loss for why the two of them are not communicating. We are dead in the water. Of course 9.1 is no longer supported, and we've been trying to budget to upgrade to 10.1.

Any and all suggestions welcome.
